Hi,
Error -99 occurs when the DAgent is unable to locate the resources on the eXpress share. This is either because,
1) The eXpress share cannot be mapped.
2) A custom startup script in WinPE has altered the current path
An F:\ drive mapping is a sure-fire way though to get and "Error -99" scenario. In automation, fixed disks, CD/DVD drives and USB media will all take first grabs of the available drive letters. This will mean that the F:\ will not be mapped and render the express share unavailable.
To resolve, ammend the automation configuration in Bootdidisk creator and set the mapping there to M:\
Kind Regards,
Ian./
